    Good Day All;
    I have question from book <SNIP>. this question in three phase circuit.

    The question is:
    Q12.30 Given the circuit in Fig. 12.53 below, find the total complex power absorbed by the load. in the attachment

    Since the load is balanced, can we ignore the impedance on the neutral path?

    Each phase sees exactly the same complex load Zph=(10+j14)Ω.

    The complex power you seek is probably the total apparent power - in Volt-Ampere. See http://en.wikipedia.org/wiki/AC_power

    This would be the sum of the three individual phase apparent powers.

    The apparent power per phase will just be (Vphase)^2/Zph
